COMPROMSE RAIL-JOINT.

To all whom it may cof/wem.

Be it known that I, JOHN H. ALLEN, a citizen of the United States, residing at East Orange, county of EsseX, State of New Jersey, have invented a certain new and useful Improvement in Compromise Rail-Joints, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying' drawings, which form a part of this specication.

My invention relates in general to rail joints, and more particularly to a joint for connecting' rails of different heights.

ln laying tracks it sometimes occurs that the adjoining rails are of different crosssection and consequently it is impossible to use the ordinary joint plates. Such an occurrence is incident to the replacing of portions ot tracks by rails larger in cross-section than the old rails forming the portions of the tracks at each side of the renewed portion. In such event it is desirable that joint plates should be employed which will securely unite and at the same time so support the adjoining ends of the rails that their tread surfaces will accurately aline.

rlhe primary object of my invention is to provide a rail joint for connecting the ends of. rails of different heights which will support the base of the smaller rail at a higher level than the base of the larger rail so that the tread surfaces will be in the same horizontal plane, and which will also resist the downward strain at the joint incident to the passage of trains. Y

A further object of my invention is to provide a rail joint plate for uniting the ends of adjoining rails of diilerent heights, which will be simple in construction, inexpensive in manufacture, and will possess great structural strength.

The two embodiments of my invention herein disclosed may be generally described as consisting of a pair of splice bars, each comprising' a vertical flange stepped up in` termediate of its ends so as to tit snugly between the heads and bases of the united rails of different cross-sections, and an outwardly and downwardly projecting flange stepped up intermediate of its ends to closely engage the bases of the rails, and a flange on Specification of Letters Patent.

Application filed April 1, 1907.

Patented Mar. 28, 1911. Serial No. 365,826.

one of the splice bars extending inwardly from the lower edge of the outwardly and downwardly projecting flange beneath the rail base and terminating beneath the lower edge of the outwardly and downwardly projecting flange on the opposite splice bar.

My invention will be more fully described hereinafter with reference to the accompanying drawings in which the same is illustrated as embodied in two convenient and practical forms, and in which Figure l is a side elevation; Fig. 2 a cross-section on line 2 2 Fig. l; Fig. 8 a cross-section on line 3 3 Fig. l; Fig. 4t a side elevation of a modilied form of my invention; Fig. 5 a cross-section on line 5 5 Fig. 4C; Fig. 6 a cross-section on line 6 6 Fig. 4t; and Fig. an elevational view of the opposite side of the joint from that shown in Fig. 4.

Similar reference characters are used to designate similar parts in the several iigures of the drawings.

Reference letters A and B designate the ends of adjoining rails united to form a joint, the rail A being larger in crossvsection than the rail B.

Referring more particularly to Figs. l, 2, and 3, reference characters D and E designate the portions of splice bars which are secured on the opposite sides of the rail A, while reference characters D2 and E2 indicate the portions of the splice bars which are secured on the opposite sides-of the smaller rail B. rEhe portions D2 and E2 of the splice bars arel stepped upwardly with respect to the portions D and E so that the vertical flanges of the splice bars are of diiierent heights to conform to the diierent cross-sections lof the united rails.

The splice bars are secured to the opposite sides of the rails in the usual manner, by means of bolts F extending through registering holes in the vertical webs of the splice bars and in the interposed webs of the rails.

Each of the splice bars is provided with an outwardly and downwardly projecting iiange adapted to closely engage the bases of the rails, such flanges being stepped up intermediate of their ends to conform to the dierent planes of the rail bases.

The portion D of one splice bar is provided with an inwardly extending ange CZ nur extending from the lower edge of the outwardly and downwardly projecting flange thereof beneath the base of the rail n, and terminating beneath the lower edge of the out-wardly and downwardly projectino flange l which forms part of the portion .lll/ of the opposite splice bar. Il. similar inwardly extending flange @his provided at the lower edge of the outwardly and downwardly pro jecting flange on the portion F2 posite splice bar, such inwardly extending flange under-lying Vhe base of the rail il and also extending beneath the lower edge of the outwardly and doumvmrdly projectN ing flange on the portion D3 of' the first splice bar. The inwardly extending flanges CZ and c2 are located in different horizontal planes so as to so support thebases of the rails that their tread surfaces will horizontally aline.

Slot-ted lugs D and E project laterally from the bases of the portions D and lf2 respectively of the splice bars. The usual spikes are driven through the slots in such lugs into the ties. Other spikes f are driven through slots in the outwardly and downwardly j irojecting flanges on the portions E and D2 of the splice bars, and through underlying holes in the base anges d and c2 respectively.

ln Figs. l to 7 inclusive l have illustrated a modified forni of my invention in which one of the splice bars is provided with an inwardly projecting flange along the entire length of the lower edge of the outwardly and dowinvardlyT projecting` flange thereof, while the opposite splice bar is provided with no inwardly extending flange.

ln Figs. 4l to inclusive reference letters A. and B indicate the end portions of adj oining rails of different cross-sections. Reference characters G and G2 designate the portions of a splice bar ver-lapping and secured to the rails at one side thereof, while reference characters lil and llt indicate the portions of a splice bar over-lapping and secured to the opposite side of the rails. rlhe usual bolts l? entend through registering holes in the vertical webs of the splice bars and through holes in the interposed rail webs. rlhe portions G2 and H2 are stepped upwardly with respect to the portions and itl of the, splice bars in order that the vertical webs of the splice bars may conform to and fit between the heads and bases of the rails. g and g2 designate the portions of a flange extending inwardlyT from the splice bar G, G2, the lportion v(/2 of such flange being stepped. upwardly with respect to the portion g so as to occupy different horizontal planes and thereby support the rail bases at levels to horizontally aline their treads. The inwardly projecting flange underlies the bases of theA rails and also the lower edge of the outwardly and downwardly projectof the opy splice bars which may eaaese ing flange of the splice bar l-l and l-lz. rllhe usual spikes j entend through slots in the outwardly and downwardly extending flange of the splice bar lfl and ll2 and 'through registering holes in the under-lying portions of the flange g and (f1. Other spikes jl extend tlnough slots in lugs H, projecting laterally from the splice bar G and G2.

ltr-oni the foregoing description it will be observed that 'l ha re invented an improved rail joint for securely uniting the ends of rails of different cross-sections comprising be conveniently made and which will possess the structural strength requisite to withstand the strain to which rail joints are subjected by reason of the passing of trains thereovcr.

- Having now fully described my invention, what l claim as new and desire to secure by Letters vPatent is:

l. ln a rail step joint, the combination with the end portions of adjacent rails of ditlerent heights, of a splice bar over-lapping the rails on one side thereof, and comprising a vertical web stepped up intermediate of its ends to fit between the heads and bases of the rails, an outwardly and downwardly projecting flange stepped up intermediate of its ends to engage the bases of the rails, and a flange extending iin yardly beneath the base of a rail to the opposite side thereof, a second splice bar over-lapping the rails on the opposite side thereof, comprising al vertical web stepped up intermediate of its ends to lit between the heads and bases of the rails, and with an outwardly and downwardly projecting flange over-lying at its lower edge said inwardly extending flange on the first splice bar, said inwaidly-extending flange being of different heights at opposite ends so as to engage with the bases of both rail ends.

2. ln a rail step joint, the combination with the end portions of adjacent rails of different heights, of a splice bar over-lapping the rails on one side thereof, and comprising a vertical web stepped up intermediate of its ends to fit between the heads and bases of the rails, an out vardly and downwardly projecting flange stepped up intermediate of its ends to engage the bases of the rails, and a flange extending inwardly beneath the base of a rail to the opposite side thereof, a second splice bar over-lapping the rails on the opposite side thereof, comprising a vertical web stepped up intermediate of its ends to fit. between the heads and bases of the rails, an outwardly and downwardly projecting flange over-lying at its lower edge said inwardly extending flangeY on the lirst splice bar, and spikes extending through holes in said inwardly eiftending flange and engagn ing the over-lying flange on thc opposite splice bar, said inwardly-extending flange lli being of different heights at opposite ends so as to engage with the bases of both rail ends.

3. In a rail step joint, the combination with the end portions of adjoining rails of different heights, of a pair of splice bars overlapping the rails on opposite sides thereof, each comprising a Vertical web stepped up intermediate of its ends to t between an outwardly and downwardly projecting flange stepped up intermediate of its ends to engage the rail bases, a flange on one of said splice bars extending' inwardly beneath the base of one rail and beneath the edge of the the heads and bases of the rails, and

outwardly and downwardly extending flange on the opposite splice bar7 and a flange on the other of said splice bars extending inwardly beneath the base of the other rail and beneath the edge of the outwardly and downwardly projecting ange on the first splice bar, said inwardly extending flanges being in different planes to support the treads of the rails in horizontal aline-ment.
